A typical Newton’s cradle consists of a series of identically sized metal balls suspended in a metal frame so that they are just touching each other at rest. Each ball is attached to the frame by two wires of equal length angled away from each other. This restricts the pendulums' movements to the same plane.
This Newton’s Cradle is a good choice as a business gift and also as a good decoration on your desktop.
Every action has an equal but opposite reaction - right before your very eyes with this fascinating Newton's Cradle Balance Balls Set. Science is demonstrated clearly and simply with a touch of amusement with this balance balls set featuring five metal balls suspended by invisible wire in a metal frame. Lift a ball, let it go and watch the ball on the opposite end move.

Newton’s cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward. The device is also known as an executive ball clicker, Newton's balls, or Newton's pendulum construction.
